l This invention relates to entrainment arresters and will be readilyunderstood from the following description of a preferred embodiment,taken in conjunction with the accompanying drawings, in which- Figure 1is a sectional elevation of a prerester; Fig. 2 is a partial plan view,with the upper half of the outer casing cut away; v;

Fig. I3 is a transverse section on the line 3 of Fig. 2;

Fig. 4 is a perspective detail of the upper end of an outer rod cell;

Fig. 5 is a sectionalplan on the line 5 5 of Fig. 4;

Fig. 6 is a front elevational detail of the lowerend of one of the rodcells; and

` Fig. Y is a transverse `elevational detail of the lower end of one ofthe rod cells.

Referring to the drawings, 10 is ahorizontal drum provided centrally ofits upper side with a vapor inlet pipe 11 and ateach end with a vaporoutlet pipe 12. Between the vapor inlet 11 and each of the outlet pipes12 is located a block 13 which occupies the crosssection of the drum 10and comprises great numbers of closely arranged vertical wires or rods14, so that the vapors passing from the inlet 11 to either outlet 12'arecompelledy to pass between a `considerable number of said wires Thevertical rods or wires 14 are suitably mounted in cells 15, which arepreferably elongated in shape so that they may be readily passed intothe drum 10 .and as- 4sembled therein. The cells are so shaped that theyco-operate to occupy completely the cross-section of the drum 10, asshown in Fig. 3. As shown in Fig. 2, a plurality, four being shown, ofcells 15 are arranged longitudinally and a plurality, six being shown,are arranged transversely so that each block 13 comprises twenty-fourcells. y

Each of the cells 15 comprises a rectilineal frame, the rods 14 beingattached to the upper and lower sides thereof in suitable man The cells15 may suitably be reinforced by stays 20. At its lower end, each of thecells 15 is provided -of the entrainment ar-- 1928. Serial No. v282,855.

with a pairof foot plates 16, which are shaped to conform to thecurvaturel of the drum 10. As shown in Figs. 1 and 3, the upper ends ofthe outermost cells`15 of the block 13, that is, the cells whichconstitute the outer faces of said block, are provided on their outersides With'plates 17 which are shaped' to conform to the curvature ofthe drum. Similar plates 18 are provided on the outer sides of theoutermost shorter cells, as shown in Figs. 2

and 3. The plates 16, 17 and 18 are suitably welded to the drum 10 andthe cells maybe welded together so as to'form a unitary block 13 whichprevents passage of the vapors from the vapor linlet 11. to the vaporoutlets 12, eX-

cept through the maze of vertical wires or rods which said blockspresent.

At its lower end, the drum 10 is provided with suitable drain pipes 19for the removal of the separated entrained liquid.

In operation, the vapors are supplied downwardly by pipe 11 and changesharply in direction toward the outlets 12. Owing to this change ofdirection, a considerable proportion of the entrained liquid is throwndown toward the bottom of the drum 10.

Droplets', which are not thus thrown out, -impinge upon the verticalwires 14 and pass downwardly thereon to the bottom of the drum 10. JIthas been found that the rate of ilow of vapors through the'blocks 13should described in connection with the s ecic de tails of a preferredembodiment t ereof, itis not intended that such detailsA shall beregarded as limitations upon the scopeof the ico means for withdrawinseparated entrained liquid from said chamer. s

2. An' apparatus for removing entrained l liquid from vapors comprisinga chamber,

an inlet for-supplying vapors to the upper side thereof, an outlet 1n aside of said chamber and remote from said inlet, and a block of verticalrods located between said inlet and outlet so 'asto occupy thecross-section of said chamber, said block com rising an assemblage ofcells, each of whic comprises a frame containing a large number ofvertical voccupy theI cross-section of said chamber,

each of said blocks comprising an assemblage of cells, each'of which comrises a frame containing a large numbero rods.
